DIGITAL FILES ONLY: 1/10th Scale COE Semi Tractor

THIS IS NOT A PHYSICAL PRODUCT! (sorry, we have to say that)

Here they are!  The downloadable files to build your own true 1/10th scale COE Semi Tractor inspired by the famous Peterbilt 362 Cab Over Engine Semi!  

Warning, BEFORE YOU DOWNLOAD: any files or start this project please watch our detailed overview on YT here. This is a 3-4 out of 5 on the difficulty scale.  You will need model building experience, need to know how to use a 3D printer/slicer, solder, use basic tools and be able to use your PC to flash custom code to an Arduino Nano (for lighting functions as show on YT).  We have a step-by-step follow a long video series on our YT channel here.  There are no written instructions.  This is not recommended for beginners or those new to RC.

This digital file pack includes all 3MF (newer version of .STL) files necessary to print your 1/10 scale COE Semi Tractor.  You will need a large format (Prusa XL, Bambu Labs H2 series, etc.) in order to print our Cab(260x263x160mm) in one piece.  We also offer the cab as a stand alone purchase{please see our other product pages).  All other components can be printed on "standard" size printers like the Prusa MK3 or Bambu P1/P2S.  The chassis jig must be split using your slicer because of its overall length/print height.  We recommend printing all components from PETG and you will need to print with TPU for things like the mud flabs, floor mats, and rear suspension air bags.

A READ-ME file will be included, but can also be found here, with descriptions and/or links of most of the non printed parts we used like the axles, transmission, shocks etc.  We will also include a file for the custom Arduino code and a wiring diagram showing the pin outs so you can solder your lights in the same manner as our YT truck.

We will soon update our Gooseneck trailer files and include an option for a "Step Deck" to be specifically compatible with this semi tractor, so you can build your own 1/10th scale semi tractor and trailer at well over 7 feet long!

Please note: Refunds are not available once you have accessed and downloaded these digital files.
